Do Not
This MSD control box did not work at all. So I called MSD to find out is there something I can do or needed to do and they said that the unit is defected just sent it back to Amazon. I could pay to ship it to MSD to have them check the motherboard that would cost me anywhere between $20 to $120 to check out the unit. They recommend that I sent it back to Amazon. Note I had a msd 6al on my car and it ran great I wanted to update my 66 Ford Fairlane,...................................Revised..........................................DO NOT BUY FROM AMAZONAs stated above I ordered a MSD control box and it did not work.Amazon has charged me $100 for the Box not working they knew it was junk when they sent it as stated from me and other buyers and still charged me do not waste your time with anything from Amazon.

Lots of features easy to use
The 1st one had a bad tach output. The 2nd seems to working great. I'm a little worried about longevity. Nice unit though with great features.
